Abstract: 298,969. Naamlooze Vennootschap Handelmaatschappij Gablon, (Cablon Corporation). Oct. 18, 1927, [Convention date]. Cables of special cross-section.-In cables of the type described in Specification 273,167 in which the lead sheath is of triangular section, the cable is rendered of a circular section outside the lead sheath by filling material. Fig. 1 shows a three-core cable of the belted type with steel tape armouring. The metallic conductors A have core insulation B, and belt insulation C surrounds all three cores. A triangular sectional lead sheath D over the insulated cables is covered with a packing F of asphalted jute to produce a circular outside section-shape to the cable.

Abstract: 432,479. Beams ; floors. BATES, H. K., 9, Allerton Road, Liverpool. Dec. 19, 1933, No. 35683. [Class 20 (iv)] A reinforced - concrete H-beam comprising a comparatively thick top flange A, a lighter bottom flange B, and a web C carrying reinforcing members F, is provided with the longitudinal edges of its top flange A so shaped as to form a tongue and grooved or rabbeted joint with adjacent similar beams wherein the tongues and grooves or recesses are discontinuous and alternately disposed along each longitudinal edge of the top flange. By this arrangement, the projections of one beam enter the grooves or recesses of the adjacent beam and relative vertical and horizontal movement between the beams is prevented. The longitudinal edges of the bottom flange B may be formed similarly to the top flange A. The beam shown in Figs. 2 and 4 is provided with spaced tongues G and grooves H between the tongues, and such formations may be arranged either beneath the upper face of the beam as shown in Fig. 2 to provide a straight joint line in the surface of the top flange, or at the upper face of the beam as shown in Fig. 2A to produce a zig-zag joint line. The upper edges of adjacent beams are spaced as at a<3>, Fig. 4, for the reception of grout. The sides of the tongues are convergent outwardly as shown in Fig. 2. The beam may be provided with transverse ribs E, D at the ends and intermediately, and openings K may be arranged in such ribs for the passage of conduits, cables, &c. The web C may be formed with openings L for the same purpose, and with additional openings to lighten the beam. Both the flanges A, B and the ribs D, E decrease in thickness from the web outwardly. Each of the side portions of the bottom flange B may have projecting wires for attaching metal lathing across the joints between the beams.

The liquid level in a liquid/vapour separator vessel 6 in an evaporator system suitable for the concentration of radio-active solutions is maintained constant by means of two interconnected vessels 10 and 12, the control being based merely on the balance of fluid in the three vessels. Vessel 10 supplies feed solution through line 17 to a boiler 4 which is connected to the separator vessel 6 and condenser 8, the vessel 12 receiving distillate through line 18 and having a distillate overflow exit 20. The level in vessel 6 is kept constant by recycling a proportion of the distillate through line 14 to vessel 10 whenever the level in separator vessel 6 drops beneath a set value. The level in vessel 6 is the same as that in vessel 10, since a pressure equalising line 22 joins the two, and may also join vessel 12, as in Fig. 1. Alternatively when vessels 10 and 12 are interconnected only by line 14 vessel 12 may be above vessel 10, as in Fig. 3 not shown. A non-return valve is provided in line 14 to prevent solution passing from vessel 10 to vessel 12.
